Currently Prometheus Exporter Module requires every RBD pool to be specified in the rbd_stats_pools option in order to gather and export their stats. This results in a couple of extra configuration step (via deployment/orchestration tool) and maintenance burden (if new RBD pools are created but not explicitly added here), while the list of RBD pools could be easily automatically retrieved from inside the Prometheus exporter.

The suggestion would be provide the following new options to allow the complementary approach (gather stats from ALL RBD pools except the BLACK-LISTED):

• Boolean option to enable automatic stat gathering of ALL RBD pools (the list should be refreshed from time to time without no manual intervention).
• Black-list to exclude specific RBD pools from the above stat gathering.
